  • the controller 100 controls the first short-circuit device 12 to perform short-circuiting, stops the frequency converter 7, and cancels short-circuiting of the second short-circuit devices 14. After the failure is eliminated, the controller 100 restarts the frequency converter 7 to set the current flowing through the first short-circuit device 12 to be zero, cancels short-circuiting of the first short-circuit device 12, and then controls the second short-circuit devices 14 to perform short-circuiting after a predetermined time has elapsed.

  • a low-cost mechanical breaker or a disconnector without a current blocking function may be utilized instead of the breaker. Otherwise, a plurality of mechanical breakers connected in parallel may be used as the second short-circuit devices 14.

Accordingly, continuous operation or safe operation can be realized without producing an arc.

  • the short-circuiting of the first short-circuit device 12 is canceled at the time t3. Since the first short-circuit device 12 is formed of a thyristor, it is not possible to cause the current to be zero even by switching a gate signal off. Accordingly, when a short-circuit canceling signal is sent to the first short-circuit device 12, the frequency converter 7 is driven, and an inverse voltage is applied to the thyristor. As a result, the short-circuit current flows from the first short-circuit device 12 to the frequency converter 7 through the resistor 13.
  • the second short-circuit device 14 is controlled to execute short-circuiting to return to the normal operation.
  • the first embodiment after a failure in the electric power system, short-circuiting of the first short-circuit device 12 is canceled, and a short-circuit current flows into the frequency converter 7 through the resistor 13, thereby reducing the current to flow into the frequency converter 7, and suppressing increase of the DC link voltage. Since the capacitor voltage at a time when flowing into the frequency converter 7 does not reach an operational threshold, the first short-circuit device 12 is not reactivated. In addition, the system can be recovered from the failure in a short time without depending on a time constant or an operation condition of the secondary winding of the wound-rotor induction machine 1.
  • the second embodiment will be explained with reference to FIG. 3 together with FIGS. 1 and 2 .
  • the same reference numerals as in the first embodiment denote the same elements, a detailed explanation thereof will be omitted, and different portions will mainly be described.
  • a semiconductor breaker is utilized for the second short-circuit device 14, instead of the mechanical breaker, as shown in FIG. 3 .
  • the semiconductor breaker is configured of a power semiconductor element such as an IGBT or a GTO and a diode connected in anti-parallel. An AC current continuously flows by connecting them in anti-series.
  • the current amount and the number of parallel connections are determined by a current flowing through the semiconductor in normal operation.
  • the number of series connections and the withstand voltage of the semiconductor breaker are determined based on voltage decrease when a short-circuit current flows through the resistor 13.
  • the number of parallel connections or series connections may increase in consideration of the case where a failure occurs in the semiconductor breaker.
  • the timings of activating and inactivating the second short-circuit device are the same as those explained in the first embodiment.
  • the second embodiment it is possible to realize high-speed short-circuiting and canceling operations by utilizing the semiconductor breaker as the second short-circuit device. This allows the system to recover from a failure in a short time when a failure occurs continuously in a short time period. In addition, it is possible to reduce the interval between t3 to t5 during which a current flows into the resistor 13, thereby reducing the capacity of the resistor.
